LEWIS 3'. BAZZONI, OF SWAMPSCOTT, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOEMACHINERY CORPORATION, OF PATERSON, NEVJ JERSEY, A CORPORATION, OF 'NEWJERSEY.

Application filed September To all whom it mag concern:

Be it known that I, LEWIS J. BAzzoNI, a citizen of the United States,residing at Swampscott, in the county of Essex and State ofMassachusetts, have invented certain Improvements in Machines forMarking Shoe Uppers, of which the following description, in connectionwith the accompanying drawings, is a specification, like referencecharacters on the drawings indicating like parts in the several figures.

This invention relates to machies for marking parts such as shoe uppers,and, more particularly, to machines for placing indicating marks uponthematerial to-designate locations for subsequent operations. The inventionmay be utilized with particular advantage in marking buttonholelocations on shoe upper material and accordingly will be discussedparticularly from this viewpoint, although, as to its more generalfeatures, it has obviously a broader field of application.

Buttonhole marking machines may be divided into two classes, gangmachines, and those in which a single marking tool is used to make aseries of marks, the tool and the piece of work presented thereto havingrelative movement between the making of successive marks. Machines ofthe latter class, to which the present invention belongs, may be of amuch simpler construction than the former and accordinglycorrespondingly cheaper to manufacture and to maintain in working order.Experience shows that but ton shoes are fashionable and are manufacturedin large quantities comparatively infrequently, only one out of aboutfour or five seasons. Buttonhole marking machines therefore stand idle alarge part of the time. A. substantial saving in the cost of the machinethen becomes important and may well be suiiicient to more than'overbalance any advantages the gang machines may have.

It is an object of my invention to produce a simple and efficientmachine for marking l'mttonhole locations on the 'buttonhole liies ofshoes in succession as the work is fed forward to a marking tool.

The number and distance apart of buttonholes upon the ,buttonhole'fliesof shoes vary greatly with changes of fashion and with differentstyles and sizes of shoes. It is therefore an object of my invention topro- MACHINE FOR MARKING SHOE 'UPPERS.

vide satisfactory means for adjusting the machine so that it may makeany desired number of equally spaced buttonhole locating marks on thework presented to it, and 'this qulte irrespective of .what the lengthof the fly may actually be, and without the necessity foranycomputationof the distance be tween adjacent buttonholes. Toaccomplish this purpose a feature of the invention lies in the provisionof means by which the machine may be operated to divide a line betweenthe locations ofthefirst and last buttonholes into the desired number ofequal parts, making an appropriate button-holelocating mark at eachpoint of division.

In the illustrated embodiment of my in- .VGIliJiOIl there is provided areciprocating work engaging member arranged to feed the workintermittently and a-marking member arranged to mark thelocations ofbuttonholes duringthe intervals in which the work is at rest. Ainovablemember is provided, exemplified as a pointer movable over the worksupport, and arranged to control the work engaging feeding member sothat the work is placed on the machine, when the marking memberiselevated and the feeding member is at its extreme forward position,withthe desired location of the first mark under the punch, and with theend of the pointer over the desired location of the last mark, theoperation of the machinewill divide the intervening distance into thatnumber of equal parts predetermined, as shown, by the form of a camsurface which controls the operation of the feeding member. As thepointeris moved to correspond to the lengths of different pieces ofwork, the distance apart of consecutive marks is, of course,

In the embodiment of my invention which I have selected for illustrativepurposes, the machine is provided with a basev plate 10 from which risetwo pairs of standards 12 and 14. Journaled in the latter is a maindrive shaft 16 driven from any suitably controlled source of power andhaving splined thereon, for sliding movement and rotation thereby, aconoidal cam 18. One end of this cam (the left hand as viewed in Fig. 2)is circular and is concentric with shaft 16. The other and larger end iseccentric with respect to the shaft and is substantially oval in form.Two portions of this end, on opposite sides of the shaft, are concentricwith the latter and are joined by a smooth curve. The least distancefrom the periphery of this oval end to the center of the shaftis equalto the radius of the circle at the smaller end. Thus the cam has oneportion which lies in the surface of a cylinder and another oppositeportion which lies in the surface of a cone.

Bearing against cam 18 is a roll 20 journaled in the end of a lever22suitably fulcrumed on a shaft 24 having bearings in standards 14. Theother end of lever 22 is connected by a link 26, to a lever 28 fulcrumedat 30 in standards 14. Pivotally mounted on rod 32 supported bystandards 12 is a member 84 provided with a removable plate 36 having acam which is held by aspring 37 against a roll 38 journaled at the endof lever 28. The general form of this cam surface and the means by whichit may conveniently be positioned and detachably connected to member 34,asby a screw 39 and a guide 'or flanges 40, are clearly shown in Figs.4, 5 and 6. The upper end of the cam surface of plate 36 is convenientlyprovided with a stop 42 made in the form of a hook to limit the upwardmovement of roll 38 as the conoidal cam permits levers 22 and 28 to moveupwardly under the influence of springs 43 which are connected to thelever 22 and to a fixed bar joining the standards 14. K

At the lower end of pivoted membersa is a pawl-like feed member 44pivoted at 46 and held in work engaging position by a spring 48. Thisfeeding member may conveniently be provided with a small handle 50 bywhich it may be moved out of work engaging position by the operativewhile a piece of work is being placed upon the bed of the machine.

Mounted at the end of an arm 52 is a marking tool, illustrated as apunch member 54, and a presser foot 56 conveniently made in the form ofa leaf-spring. The marking tool is moved alternately into and out ofwork engaging position by means of a cam 58 mounted on and rotated bythe main drive shaft 16 and engaging the arm 60, spring held as at 61,and rigidly connected to asuitably journaled rock shaft 62 to which arm52 is rigidly connected.

The bed of the machine may conveniently be provided with an arcuatescale laid off in inches or other convenient units, as illustrated atthe right hand end of Fig. 1. Over this scale moves the end of a pointer64 pivoted at 66 to the bed of the machine and having rigid therewith apulley 68 around which passes a belt 70 supported by suitable idlers 72and 74 and connected wit-h a cross head 7 8 slidably mounted upon rods79 and provided with a fork engaging a grooved collar 82 on one end ofthe conoidal cam 18 for sliding the same on drive shaft 16 as thepointer 64 is moved from one position to another. Idler 74 mayconveniently be supported by an adjustable member 84 to provide asuitable belt tightener, the member 84 being pivoted to the frame andheld at the desired distance therefrom by a screw bolt as shown in Fig.2.

In the operation of the machine, the work, for instance the buttonholefly of a shoe, is placed on the bed of the machine at that stage in thecycle of operation thereof at which the marking member is in itselevated position and the feed member at its extreme. forward position,as illustrated in Fig. 4, with'the location at which it is desired tohave the first mark directly under the marking tool 54 and with the edgeof the work in approximate alinemeut with the scale on the bed of themachine. This may be facilitated by swinging the feed member upwards bymeans of its handle 50. Pointer 64 is now adjusted so that its end isdirectly over the desired location of the last buttonhole. Power isthen; applied and the work fed step-by-step through the machine. Betweensteps the punch is lowered through the work. The feeder 44 movesrearwardly and stops, as shown in Fig. 5, the punch holding the workagainst displacement. The punch thereupon rises, after which the feedermoves forward, taking the work with it, and stops, as shown in Fig. 6,whereupon the punch is again lowered through the end of the :pointer.

work. This cycle of operation is repeated 'thenumber of times necessaryto make the throughout its length having a curvature concentric with thedrive shaft so that teeding member 44 will have a short pause at bothextremes of its -movement, while the markingtool 54 is being moved intoand out of work engaging position. During the rearward non-feedingmovement of the feeding member 44 the work is held against undesireddisplacement by the marking tool 54 The ment when'the marking tool isbeing with drawn.

The cam surface of plate 36 is so formed thatthe feeding movements ofmember 44 are equal aliquot parts of the distance between the markingtool and the end of the pointer, irrespective of the position of theThus if it is desired to mark the location of 12 buttonholes. asillustrated inFig. 8, there will'be 11 equal steps of the feeding member44 to move the work through the distance between the first and the lastmark.

To effectively operate the machine all that is necessary for theoperative to know is the desired location or the first and last buttonholes togetherwith the number of buttonhole locations to be marked.

The-movement of pointer 64 to correspond to the lengths of differentpieces of work slides the conoidal cam 18 on its shaft and so varies theamplitude of the oscillations of lever 28 and accordingly'of pivotedmember 34and the work feeding member 44. If it is desired to makesome'other number of marks it is necessary to remove cam 36 andsubstitutetheretor another cam of generally similar form but with itssurface so shaped as to move the pivoted member 34 a greater or lessdistanceas the case may be when lever 28-is'osc11lated through agivenarc. It 1s necessary to provide as many of these cam bearing plates36 asthere-are different numbersot 'buttonholes to be marked on thedifferent pieces of work. For this reason the machine is so arrangedthat these cam bearing plates -36 maybe easily and quickly changed so asnot to unduly delay the operation or the machine.
